Overview
Rmc 15mm 850kpa Pressure and Temperature Relief Valve is a safety device designed to prevent over-temperature and over-pressure in unvented water storage systems.
The RMC 15mm 850kPa Pressure and Temperature Relief Valve serves as an auxiliary pressure relief device, ensuring that pressure does not build up in the event of a blockage in the drain line. This valve is suitable for both horizontal and vertical installations and is individually tested and calibrated for reliability. It is dezincification resistant and meets Australian Standards for potable water, making it a critical safety control for pressurised unvented water heaters. In case of failure of normal thermostatic controls, this valve ensures that the water temperature does not exceed 99° C, thus safeguarding against potential hazards associated with over-temperature and over-pressure in unvented containers.
